BRUSH;

SPECIFICATION forming part of Letters Patent No. 637,680, dated November 21, 1899 V 7 Application filed November 18, 189 7. Serial No. 658,990. (No model.)

To all whom it may concern.-

Be it known that I, DANIEL W. TOWER, a citizen of the United States, residing at Grand Rapids, in the county of Kent and Stateof Michigan, have invented a new and useful Brush, of which the following is a specification. r

This invention relates to fountain-brushes which are supplied with a composition or substance contained in a collapsible tube, and is more particularly designed as an improvement on the brush disclosed in Patent No. 570,57 3, granted to me November 3, 1896, although it can be applied to brushes of the Variety of which that shown in my patent is typical.

The casing for inclosin g the collapsible tube is elliptical in cross-section to accommodate the flattened end of the collapsible tube, and the latter making screw-thread connection with the brush or part fitted thereto it is of the utmost importance that the flattened end of the collapsible tube be in a plane parallel with the back of the brush when the said tube is screwed up tight against the part to which it is fitted.

One of the chief objects of this invention is to insure the collapsible tubes being closed, so that when applied to the brush or the part fitted thereto the flattened end will correspond with the major axis of the handle or casing when the latter is in place. This result is effected by flattening the opposite sides of the cap end of the tubes, these flattened portions bearing a relationto the threaded end so that when the latter is screwed home tightly the flattened or closed ends of the tubes will be in a position to correspond with the longer diameter of the casing.

A further purpose of the invention is to construct the brush-back so that its opposite ends will be similarly formed and of corresponding taper, whereby the brush can be reversed end for end and fitted to the part receiving the casing and handle.

The improvement further consists in the peculiar construction of the brush-back with relation to .the means for securing the tufts thereto.

Fora full understanding of the merits and advantages of the invention reference is to be had to the accompanying drawings and the following description.

The improvement is susceptible of various changes in the form, proportion, and the minor details of construction without departing from the principle or sacrificing any of the advantages thereof, and to a full disclosure of the invention an. adaptation thereof is of the brush, having a portion of the cap.

broken away. Fig. 4 is a transverse section of the brush and the head which is detachably fitted thereto, taken on the line at w of Fig. 2. Fig. 5 isa detail view in perspective of a collapsible tube. Fig. 6 is a detail view in perspective of the casing for the brush, parts being broken away. Fig. 7 is a transverse sectional view taken on the line y y of Fig. 2.

Corresponding and like parts are referred to in the following description and indicated in the several views of the drawings by the same reference characters.

The invention is designed to be applied to the various styles and kinds of brushes and for the sake of illustration is shown in connection with a tooth-brush, because it is best adapted for brushes of this type.

The brush-back 1 is a metal block having rows of perforations'to receive the tufts, which are drawn into the openings by wire and secured therein in the ordinary manner. This back is formed with a rim or flange 2 of a height to project beyond the wire employed for'securing the tufts to the back and incloses a space which is filled flush with the top of the rim by plaster-of-paris or like cementitious plastic material 18, which protects the inner ends of the tufts and the wire securing the same. The edges of the back are beveled inwardly, and the ends are made rounding, and the back tapers slightly from an intermediate point toward its ends. A cap 3 is fitted to the back and extends over the filled 7 or top side thereof, and its edge portions are bent or swaged, so as to snugly embrace the;

beveled edges of the brush-back and correspond to the taper and bevel thereof. A flexible nipple 4-is located centrally and comm unicates with anoopening extending through the back and cap. The head 5 is provided.

' flexible nipple 4, and conveys the substance to the brush from the collapsible tube.- T h"ef outerend of the tubular stem 7 is flattened, so as to appear oblong in transverse section,

and the opening therein is internally threaded to receive the threaded end 10 of the collapsible tube 11, which latter contaifis the dentifrice, composition, or substance to be supplied tothe brush. The side portions of the flange 6 are slightly divergent to correspond to the convergent edges of the brush-back, thereby'enabling the head to slip easily upon the brush-back to within a short distance of the limit of its movement, when considerable en'- ergy must be exerted to force the head into gaging surfaces will be sufficient to prevent the disengagement of the brush from the head 'tects the collapsible tube 11.

The collapsible tube 11 has the cap end reduced and threaded, as shown at 10, and the sides adjacent to the shoulder formed at the base of the threaded end 10 are flattened, as shown at 13, and these flattened portions 13 are disposed with reference to the threaded portion 10 so that when the latter is screwed firmly into the'threaded portion of the stem 7 they will occupy a position corresponding to the top and bottom sides of the brush. After the tubes have been filled their rear ends are closed by being pressed together and folded,the flattening being accomplished with reference to the flattened sides 13 so that when the collapsible tube is fitted to the head 5 or its stem the flattened end 14 will occupy a position corresponding to the major axis of the handle or casing 12. It will thus be seen that the collapsible tubesare not closed at haphazard, but systematically and with reference to the threaded or cap end, so that when the tube is properly positioned with reference to the brushi'tsflattened or closed end 14 will extend and correspond with the major axis of the part 12. As will be understood, the object of flattening the collapsible tube, as at 13, is

' to indicate that the tube is to be closed, so as to dispose the broadened end thereof in a proper relative position to fit withinthe major axis of the casing or handle. Anyother'su'itable or convenient means or mark maybe used to indicate how the closed end is to be disposed.

' The housing or casing 15 is constructed to inclose the brush on four'sides, the rear end and side corresponding to the back of the brush beingopen, and the walls of this housing areperforated for the admission'of air and the escape of moisture, thereby preventing the molding and souring of the brush. The upper edges of the sides and end are formed with a bead 16 to receive the edges of the brush-back, and the rear portions of the side beads are olfset, as shown at 17, to receive the edges of the head 5, which latter when in position projects beyond the edges of the brush-back, as will be readily under-v stood. i h

In a brush, the back provided with an inclined circumscribin g flange forminga 'cavity and with the tuft-perforations,[tufts of bristles secured in said perforations, the cementitious material filling theg'cavitywithin the back, and a head fitted over the back to inclose the cementitious material and protop side and its edges inwardly beveled, tufts secured to the back by wire in the ordinary manner, plastic cementitious material filled into the space inclose'd bythesaidflan'ge and coming flush with the upper edge thereof, and

a cap fitting over the filling and having its edge portions bent or swaged to snugly embrace the beveled edge of the back, substantially as set forth.

4. The combination with a brush-back, of a detachable head in sliding frictional engagement with the brush-back, and a detaehable perforated casing having an open inner end, said casing having along the upper edges of its side walls longitudinal grooves adapted to receive the edges of the brush-back and the head, and'the walls of the grooves being adapted to frictionally engage the two parts to hold the perforated casing in place, substantially as described.

In testimony that I claim the foregoing as my own I have hereto afiixed my signature in the presence of two witnesses. V

DANIEL W. TOWER.
